US and UK Liquid Measurements

There are quite a few major differences in the way that different countries use to measure liquid volume.

The terms "pint" and "gallon" can mean different amounts of liquid depending on which country you are in.

The information below will tell you a few of the main differences between the way liquid volume is measured in the US and the UK.

US Customary units and UK imperial units are compared below.

US and UK Differences

How much is a fluid ounce?

In both the US and the UK, a fluid ounce is about 30ml of liquid.

However, in the US it is 29.6ml, and in the UK it is about 28.4ml, so there is still a small but significant difference.

How much is a pint?

In the US, a pint is 16 fluid ounces, or about 473ml.

In the UK, a pint is 20 fluid ounces, or about 568ml.

How much is a gallon?

In the US, a gallon is 8 pints, 128 fluid ounces or about 3.8 liters.

In the UK, a gallon is 8 pints, 160 fluid ounces, or about 4.5 litres.

These differences can lead to quite a few problems when it comes to comparing quantities or prices per gallon in different countries!
